Here is a collection of posts relating to 4age rods, covering what engine has what rod and some pics of what they look like:

I used to think that the orange and green tictacs gave you special powers. The orange ones would make you stronger and the green ones would make you faster. So i used to eat some green ones and run around my lounge as fast as i could, then eat the orange ones and try to pick up the sofa. I wish it were true!

I've got a growing collection of 4age connecting rods... blacktop, silvertop, smallport, bigport.
I've nearly got one of each type so we can have a good collection of pics.
Hopefully this will help people identify what rods they have and what ones the might want to run in their engine.

Dan (DraggerDan) has given me a bluetop rod. I will include it in the pics a soon as I can.
Weights - working on this also.

Adrian (acesniper) and I took a box of goodies to my work and got permission to use a set of accurate scales.

Just went to work with all of my rods and pistons and weighed them.
I've kept them in groups of parts from the same engine - this is so I can sus out how toyota makes balancing their engines simpler. I figure that they just stamp out 1000's of rods each day and just sort out groups of very similar weights... Looking at the results it seems that some groups are pretty close... and others not.

All you conrod geeks - read this article that discusses powder forged rods vs drop forged rods
http://www.metal-powder.net/business/ar ... jun05.htmlPowder forged rods are better in many aspects.
An interesting part of this document relates to failure of powder forged rods:

"Powder-forged rods typically failed at or near the minimum cross-section of the I-beam, where both surface and sub-surface crack-initiation sites were observed. Drop-forged connecting rods were found to fail in a less consistent fashion, which scanning electron microscopy revealed to be related to defects such as oxides, folds and microcracks. This could explain the much larger scatter of fatigue strength values exhibited by the drop-forged rods."

Sounds like the Blacktop rods could be produced using the powder forged method as this could explain why they all tend to fail in the same place??
PM me any comments

Also - does anyone have pics of failed 4age rods?
